Title: Rotary positive-displacement fluid pump or fluid operated motor
IPC: F04C2/10
Filed: 1969-03-31
Abstract: 1,235,395. Rotary positive-displacement pumps and motors. GERMANE CORP. March 31, 1969 [Dec.31, 1968], No.16838/69. Heading F1F. A pump, or motor, has a star member 25 rotatable in a planetary manner while meshing with a fixed ring-member 24 and coupled to a powerinput, or output, shaft 38 by a splined member 54 abutting a ring 60, flow of working fluid e.g. oil, between inlet and outlet ports 18, 19 and cells 29 being controlled by a rotary valve-member 31 connected to the shaft by a shear pin 52 engaging with a slot 53 permitting limited axial movement of the valve member relative to the shaft. The valve member is supported by the wall of a bore 15 and separated from the shaft by an annular gap of width X, the shaft being supported by bearings 40, 41 situated between thrust bearings 49, 50. The aforesaid gap relieves the valve member of radial loads on the shaft, the bearings or the shaft being replaced when a radial load 64 renders the width X<SP>1</SP> of the gap at either end thereof zero. The bearing 41 may be replaced by a self-aligning bearing (67), Fig. 5 (not shown); and the pin 52 may be replaced by a spring (80), Fig.6 (not shown), which collapses when the torque transmitted thereby becomes excessive. A conduit 61 and passage 62, 63 facilitate lubrication of the bearing 41 by the working fluid leaking from the high-pressure regions. The valve member has annular grooves 33, 34 in register with the ports 18, 19 and intersecting alternate slots 35, 36, respectively, which slots during rotation of the valve member periodically and sequentially communicate with the cells through corresponding openings 21 and passages 20.

Title: Improvements in or relating to element-positioning mechanisms
IPC: F15B11/12
Filed: 1963-04-30
Abstract: 960,399. Fluid-pressure apparatus. HOUDAILLE INDUSTRIES Inc. April 30, 1963 [May 14,1962], No. 16982/63. Heading F1P. A mechanism for relatively positioning a pair of elements comprises a plurality of groups of actuators, each group consisting of four individually actuatable fluid actuators, the actuators of each group having individual full travels which are integral multiples of the shortest full travel of the group, all the actuators being mechanically connected together in a single series one end of which is supported and the other end being adapted to be coupled to one element for moving it with respect to the other element by any amount defined either by any of said full travels or by the sum of any combination of said full travels. In Fig. 1 an element 45 secured to e.g. a workpiece is adapted to be positioned relative to a tool fixed with respect to a pair of fixed rails 46, 47. The element 45 is movable in a direction parallel to the rails by five groups of fluid actuators 12-31 slidable on a fixed guide 11, and is movable in a direction perpendicular to the rails by a similar group of actuators 33-40 slidable on a guide 32 itself movably supported on the rails 46, 47. The numerals appearing on the actuators represent the ratio of the full travels of each actuator to each other actuator, and the shortest full travel of each of the groups is effectively ten times as large as the next smaller shortest full travel of another group. The actuators 12-15 are slidable perpendicularly to the actuators 16-31 and move a wedge 48 which engages a cam block 50 connected to the actuator 16 to thereby multiply the effect of the movement of these actuators by onetenth. The actuators 33-36 operate through a similar wedge 51. Each actuator is independently controlled by a separate solenoid operated valve, two of which valves 87, 88 are shown controlling actuators 18, 19. Each actuator, Fig. 2, comprises a cylinder 56 and a piston 60 having a hollow piston rod 61 which extends from one end of the cylinder and is secured to the cap 59 of an adjacent actuator so that pressure fluid continuously supplied from a pump 82 to the hollow piston rod of the end actuators 12, 15 is effective to extend all the actuators of the series. Retraction of a particular actuator is then effected by operation of the appropriate solenoid valve whereby fluid at a higher pressure than that supplied by the pump 82 is supplied from a further pump 85 to a port 79 to thereby fully retract the actuator against the resistance of the continuously maintained lower pressure fluid. The piston 60 is cushioned at one end of its travel by a cylindrical portion 77 on the piston co-acting with a recess 78 in the end of the cylinder and at the other end of its travel by an end 68c of the adjacent piston rod co-acting with a recess 65 in the piston 60. A series of actuators may be adapted to move a rack to thereby rotate a workpiece, a further series of actuators being provided for radially positioning a tool relative to the workpiece.

Title: Analogue-digital converting apparatus and method
IPC: H03M1/00
Filed: 1970-04-09
Abstract: 1311933 Electric selective signalling system TAKEDA RIKEN INDUSTRY CO Ltd 9 April 1970 [9 April 1969 24 Feb 1970] 17001/70 Heading G4H In an anologue to digital converter an input signal is integrated until the integral reaches a predetermined threshold level whereupon the input signal plus a reference signal of opposite polarity is integrated to return the integral to a starting threshold, during the return clock pulses are Counted, the cycle being repeated for a predetermined time at which a digital representation of the final value of the integral is added or subtracted to the accumulated count of clock pulses to provide the digital form of the input signal. Imprecision due to non-linearity in the integrator range is thereby avoided by integrating only over a narrow range between the threeholds. In the arrangement of Fig. 3 there is an additional intermediate threshold at which a larger reference voltage is integrated to return the integral to the starting threshold. The analogue signal at P is integrated (I) until it reaches a first threshold determined by detector Da, or Db if in the opposite direction, whereupon controller K closes switch Sa or Sa<SP>1</SP>, to integrate the reference voltage E or E1 as well. Clock pulses from oscillator o are frequency divided at F and pass to a counter N. Upon the second threshold being reached as determined by Db, or Db<SP>1</SP>, switch Sb or Sb<SP>1</SP>, clones to integrate double the reference voltage and clock pulses of double the former frequency are counted. On the integral returning to the starting threshold as determined by detector Do all switches except So open and the cycle repeats. After a predetermined time switch So opens, switches Sb and Sa close and the integral returns to the starting threshold while the counter is still counting high frequency pulses. The final value of the accumulated count is the required ditial signal.

Title: Float actuated fluid control valves
IPC: F16T1/24
Filed: 1958-05-29
Abstract: 857,206. Steam traps. JORGENSEN, E. April 15, 1959 [May 29, 1958]. No. 17135/58. Class 64(2) [Also in Group XXIX] A float-actuated valve, e.g. a steam trap, comprises a hollow body 3 with an inlet 5 and an outlet 4, the latter being provided with a member 6 having a bore 7 and a spherical upper surface; the member 6 holds a bracket 8 with a horizontal U-shaped stirrup 9 between the limbs of which is a rocker 10 fixed to a float 11. The rocker 10 incorporates a bore in the upper end of which is threaded a plug 12 that co-operates with a loose ball 13 retained in the lower end of the bore and forced by the plug 12 to protrude from the lower part of the bore. Between the stirrup limbs are two pins 14, 15, the latter coacting with a heel 10a to act as an abutment for the rocker and the former passing through the rocker with its ends in slots in the stirrup. With the ball 13 closing the upper end of the bore 7, as shown, the rocker is horizontal and its lower surface is slightly spaced from the spherical surface of member 6. When condensate fills the body the float 11 rises and angularly moves the rocker 10 which firstly turns upon the ball 13 and then upon the spherical surface as constrained by the pin 14 in its slots, the fulcrum moving gradually further away from the ball so increasing the ballfloat movement ratio. Between the plug 12 or some other part of the rocker 10 and the body 3 is a looped or corrugated bimetal strip 16 which when hot permits the valve to close gravitationally; when the strip 16 is cold it acts to open the valve so that air and condensate are discharged quickly and an air-lock avoided when the steam is first turned on. Specifications 768,720 and 797,675 are referred to.
